AI 'Brain Clock' Links Inequality and Pollution to Accelerated Brain Aging

• Study reveals 'brain clock' can determine if brain ages faster than chronological age
• Women, countries with high inequality, and Latin American nations show faster brain aging
• Research analyzed brain scans from 15 countries using AI to measure functional connectivity
• Alzheimer's and dementia patients had larger 'brain-age gaps' than healthy individuals
• Findings suggest socioeconomic factors and air pollution contribute to accelerated brain aging
